Uses

Organosilicon Electrolytes for Lithium Ion Batteries

1. Silicon based electrolytes with polyethylene glycol oligomers improve thermal and electrochemical stability of lithium-ion batteries;
2. Increases battery long-term stability;
3. Are less flammable than conventional organic carbonate-based solvents and maintain the safe operation of batteries;
4. Improves conductivity and kinetics of the lithium salts;

Electrochemical and Physical Properties:

1. Viscosity 2.0 cP at 25°C; Conductivity of 0.8M LiBOB electrolyte: 1.29 x 10 –3 S cm–1 at 25°C.Boiling point 245°C; Glass transition temperature -110°C.
2. Soluble electrolytic lithium salts: LiBOB, LiPF6 (03-0325), and LiTFSI
3. ANL-1S1M3 is non-hydrolyzable and less flammable than the alkoxysilane counterparts.
4. ANL-1S1M3 electrolyte cell test demonstrated good cycling performance in lithium-ion batteries, with a charge and discharge rate of C/5, cycled between 3.0 and 4.2 V at room temperature with only 9% capacity loss over 200 cycles.
